To all who/m t mag/romera.'

Be it known that we, YDAVID M. SULLIVAN and GEORGE W. BAITY, citizens of the United States, residing at,Greensboroin.the county of Guilford and State of North Caroli-na, have invented new. and .useful Improvements in Spinning Machinesof 1ri'liich the ,following is a speciication.

This invention .relates to spinning machines, and more particularly to the zconstruction of lthe spindle Arail .and .the arrangementof the 4spindles thereon.

The invention contemplates an. attachment for the usual .spindlerailhavingfa series or li-ne of spindles .extending longitudinally thereof, and hasas .its'object the provision of means which Awill permit the Vspindles to be positioned in staggeredrelation thereby separating furtherthe adjacent spindles and preventing the entanglement of the threads.

SpindleA rails havingsthe--spindles arranged in staggered relationare old and well known in the art, butso yfanas we are aware there has not been providedfheretofore an attachment which will .enable -,the spindles to be relatively positioned in -f this manner upon the ordinary and usual spinning rail having a single line of spindles thereon. The'inventioncomprises, broadly, a. rail extension plate having means for supporting a seriesof'spindles adjacent the series of spindlesupon the rail and comprising' -means permitting the extension to `be readily vsecured to the-main rail.

More specifically, the invention provides for the elimination ofr alternatespindl'es upon the rail` and the-positioning of these upon the extension plate. v.The means for securing the extension to the rail is preferably ofa character that will permit the ordinary bolster case openings in the rail, and f-rom which the eXtension-platespindles are removed,'to be employed in connecting the extension .to the main rail.

. A further' object-ofthe invention relates tothe particular character of thefmea-ns for connecting fthe extension 'to the rail, which preferably affords a compositerail vhaving a smooth and unbroken surface.`

In the accompanying drawings .there is shown one form of a device in which the invention may be embodied, and in these drawings Fig. l is a front elevational view of a portion of a spinning machine,

Fig. 2 is a top plan, l

Fig. 3 is atop plan view :with their-ring a rail removed, y Y F ig. I is a cross section on the line of Fig. 2, 1 Fig. 5 is a section on the linej5-5 of Fig. 3, and v Fig. 6 is a bottom plan view oftherail extension. l f

Referring to the drawingsmore in detail, 10 indicates, generally, the fnamejof the machine, which .supports a spindle Arail. ll. In the drawings the illustratedV rail is of the usual type having va .plurality ofopen ings 12 therein toreceivefbolster cases 13 which are secured in position by means .of locking nuts 14 beneath the` rail. .'Ilhe'gbol- .ster cases and spindles 15,1whichare`driven by means of the whirls 16, are-arranged in spaced relation longitudinallyfof the rail.

In operating such a machine itis found that the threads tend to ,'ball'orornfandv in order toavoid entanglement of the threads being wound upon ladjacent spindles various types of strandA guarding-meansyare employed. AThe present' invention contemplates a different arrangement ofthe spindles upon the rail, and for this-purpose a rail extension bar 17 is lprovided and .the same has` formed rtherein a plurality of openings 18 adapted to receive bolster cases. 'Ifhe bar. 17 carries .fa plurality of .lugs`119 projecting from one edge of the same beneath the spindle rail, the lugs vhaving therein openings 20V which lregister with; several bolster case openings in theamain rail. Bolts 2l pass throughthe registeringvopenings and'serveto loclr lthe-'extensionto[the main rail with its inner longitudinal edge 22 abutting the face offthe rail. lIt will be noted ffrom an `inspection lof :Figi-:5 that when the extension and rail are heldin fixed position a composite rail construction having a smooth, unbroken top surface 4is provided. f

In -securing the extension? to fthe rail lit fis desirable -to moveA a number of the main rail spindles, preferably every other `spindle, and these, together with tlieirbolster cases, vare positioned inthe openingsin the extension as `shown in Fig.` 3. .This` arrangement provides a .series or feline of :spindles on gthe extension :paralleling 'the4 line of-.spindles on the rail; with y"the spindles of the two series arranged in staggered relation.

By reference to Figs. 2 and 4 it will be noted that the invention includes a Common ring rail for the two series of spindles; ythe ring rail 25 is formed with two parallel series of openings 26, 27 adapted to receive the travel rings 28 and is operated by the usual pitman 30 constituting part of the actuating mechanism for the machine.

It will be noted that the extension bar may be readily applied to the ordinary machine by simply removing a number of the spindles and bolster cases from the rail. lt is not necessary that every other spindle be removed, or that the exact number or securing lugs 2O be provided as indicated in the drawings; however, such a construction affords the staggered relation of the spindles, which is desirable in order to maintain the proper distances between the adjacent spindles. It should be understood that numerous modifications may be made in the illustrated and described form' without departingv from the scope of the invention, which is more definitely deiined in the following claims. v

4We claimzwv 1. An attachment for the usual spindle rail carrying a series of spindles comprising a rail extension having means for supporting a series of spindles in staggered relation to the main rail spindles, and means for securing-the extension to said main rail.

2. An attachment for the usual spindle rail lcarrying a series of spindles comprising a rail extension having means for supporting a series of spindles in staggered relation to the main rail'spindles, means for securing the extension to said main rail, and a ring rail common to said' main rail and its extension.

3. An attachment for the usual spindle rail adapted to carry a series of spindles, comprising a rail extension and means for securing said extension in position adjacent the main rail, said extension being adapted to support a line of spindles in parallelism with the series of'main rail spindles.

4. An attachment for the usual spindle rail adapted to carry a series of spindles, comprising a rail extension and meansy for securing said extension in position adjacent the main rail, said extension being adapted to support a line of spindles n parallelism with the line of main rail spindles with the spindles upon the rail vextension positioned between the spindles of the main rail.

5.A spindle rail extension comprising a bar having a series of openings therethrough and lugs projectingpfrom one side thereof adapted to serve as means for securing the extension to a spindle rail. Y

6. A spindle rail extension comprising a bar having a series of openings therethrough position adjacent a spindle rail with the edge of the extension bar abutting the edge of the rail to form a smooth rail surface.

8. An extension for a spindle rail having bolster case openings* comprising Va bar adapted to carry a series ot spindles, and lugs extending from one edge of said bar, said lugs having openings adapted to register with the bolster case openings on a spindle rail. I 9. An extension for a spindle rail having a plurality of bolster case openings comprisinga bar` adapted to carry a series of spindles, lugsv extending from one edge of said bar and having openings 'adapted to registerwith the bolster case openings on a spindle rail, saidlugs being offset fromthe plane of said bar.

10. The combination with a spindle rail having a seriesof openings to receive bolster cases, of a rail extension secured to said rail and having "lugs provided with openings registering with some of the bolster case openings in said rail7 said rail extension having a series of openings whereby the extension'is adapted to support a plurality of spindles. f

11. The combination with a spindle rail and a series of spindles thereon, of a bar secured to said rail with a line of spindles thereon yin parallelism with the seriesl of spindles on said rail, said bar having a plurality of lugs extending beneath said rail and serving as` means to connect the bar to the rail.

12. The combinationv in a spinning machine, of va spindle rail',`a seriesof spindles on said rail, the rail having openingstherethrough betweensaid spindles, a bar having itsedge facing thelongitudinal edge of said rail, l'ugs on said bar projecting beneath the rail and having openings registering lwith the openings in said rail,'fastening means passing through said registering openings, and a series of spindles on said bar paralleling the series of spindles on the rail, the spindles of the two series being positioned in staggered relation. j
